This paper presents a study on the seismic evaluation and retrofit of limited ductile reinforced concrete (RC) buildings, which make up the bulk of built infrastructure in the central building districts and high-density residential areas in Australian cities. In low to moderate seismicity regions such as Australia, RC buildings will have structural elements that have been designed with limited to no ductility. The individual building needs to be assessed and ranked for their retrofitting priority. An assessment for retrofitting methodology involving a three-tiered approach will be introduced in this paper. The assessment framework including a tiered approach was developed to evaluate the potential vulnerability of Australian RC buildings and to facilitate decision making in relation to the need for seismic retrofitting. Structural threshold values related to the vulnerable features introduced in the framework were also investigated to support the identification process of the method. It is expected that the developed three-tiered methodology will provide a significant contribution to the seismic evaluation and retrofit of existing RC buildings in Australia.
